Download or read book Distribution of Bowhead Whales in Relation to Hydrometeorological Events in the Beaufort Sea written by Denis H. Thomson and published by King City, Ontario : LGL Limited. This book was released on 1986 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial surveys of the summertime distribution of bowhead whales in the southeastern Beaufort Sea have shown that the distribution of bowheads has been quite variable over the four years of study, 1980-83. This report presents the results of an investigation of the relationship between the observed distribution of bowhead whales in the Canadian Beaufort Sea and the physical and meteorological patterns that might affect the distribution of zooplankton in the Beaufort Sea. The overall aim of this study was to identify easily-monitored parameters that could be used to predict bowhead whale distribution.

This book was released on 1987 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bowhead whale is a large, baleen whale found only in Arctic and sub-Artic waters. It is now one of the rarest cetaceans and is currently considered an endangered species. During August and September whales are present in areas of offshore oil exploration activity in the southeast Beaufort Sea. Aerial systematic and photogrammetric surveys were conducted in the southeast Beaufort Sea during August and September 1986, to investigate the distribution, relative abundance, and age segregation of the whales in relation to petroleum activites in the region. Two systematic surveys of the study area were completed from August 25-September 1 and September 7-14. Photogrammetric surveys of portions of the study area were conducted from August 25-September 1. Bowhead sightings recorded by researchers and by industry personnel during 1986 were also examined.

This book was released on 1986 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the spatial distribution, relative abundance, and age segregation of bowhead whales in relation to petroleum industry activities and oceanographic features in the south-east Beaufort Sea during the 1985 open water season. Surface oceanographic conditions at the time of the aerial surveys (August-September) are described using satellite imagery analyses and in-situ temperature and wind data from industry vessels. Aerial photographic surveys provided information on the age/size class distribution and site tenacity of bowhead whales within the study area. Bowhead sightings recorded by other researchers working in that area during 1985 are also examined. Comparisons are made with results of previous bowhead whale surveys in the area.

This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The overall objective of this study was to investigate the relationships between the distribution of bowhead whales in the Beaufort and Chukchi Seas and oceanographic features visible in satellite images. Particular attention was to be paid to the Pt. Barrow area ... we first examined the timing of the fall migration for the years 1979 to 1986, and compared it to variations in environmental conditions in those years. ... We also investigated local environmental conditions at Barrow, to determine if the feeding in that area might relate to some observable oceanographic phenomena. ... we also studied the relationship between the end of the peak migration past Prudhoe Bay and a number of environmental variables. ... A brief analysis of the very large annual variations in the timing and geographic nature of break-up and the duration and extent of open water was also conducted ... --Summary.

McLaren and published by Ottawa, Ont. : Environmental Studies Revolving Funds. This book was released on 1985 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systematic aerial surveys were conducted in the southeast Beaufort Sea on 19-24 August and 6-11 September 1983 to document the numbers and distributions of bowhead whales and of other marine mammals. The study area extended from 141 W (Alaska-Yukon border) eastward to 128 40 W (near Cape Bathurst), and from the 2 m depth contour northward to about 25 km north of the 100 m depth contour, except between 141 W and 138 W where the northern boundary was at 70 20 N. The northernmost 25 km sections east of 138 W also extended beyond the 200 m depth contour, and thus included the steep shelf break beyond the shallow continental shelf.

This book was released on 1989 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compares the behaviors of the Eastern Arctic (Davis Strait-Baffin Bay) bowhead whales to that of the Western Arctic (Bering-Chukchi-Beaufort) stock. Whales were observed when feeding in deep water, socializing in shallow water, and migrating. Discusses factors, other than environmental conditions, which affect behavioral differences.
